Patented Mar. 15, 1921.

Application filed September 18, 1918. Serial No. 254,634.

To all whom it may concern:

Be it known that I, PHIROZESHA\V hLlUN: UHERJI Mei-rm, a subject of theEmperorot India, residing at Bombay, India have ini'ented certain newand useful improvements in Ships, of which the following is aspeciiication.

This invention relates to ships or vessels with the object of renderingthem unsinkable WAGE struck by a mine, torpedo or other explosive.

The invention consists in providing antight compartments between theupper and lower decks the space below the lower deck being occupied toany desired extent with c\ -JlhlllCiil airtight tanks which areenveloped in sea water. The sides of the ship below the level of thelower deck are composed of network culate around the tanks.

The invention is represented in the annexed diagrammatic drawingsapplied to a battleship.

Figure l is a cross section of a ship constructed according to thisinvention and taken on the line 1 l of 2, which latter shows in ageneral way the internal arrangement of the ship. is a side elevation ofthe ship partly broken away, illustrating the network structure.

Airtight compartments i are provided between ,t ie decks c and (Z forvarious uses and the engine and boiler a are placed in a caisson 6 whichis watertight. The space below the deck 7. is occupied to any desiredextent by cylindrical airtight tanks 9 in two tiers both of which areattached to the deck fr amto allow the water to cir-' ing 6 and thewhole are suspended from the deck (Z. These are also attached to thebottom it of the ship forming a strong mass resembling somewhat thestructure of a honeycomb. The sides of the ship below the level of thedeck d are composed of a very strong network f admitting the sea freelybetween the cylindrical tanks. This network will also offer considerableresistance to the impact of a torpedo. The forward and after ends of theship will be plated to facilitate navigation.

What I claim as my invention and desire to secure by Letters Patent is:-

1. A ship comprising a series of airtight tanks ar 'anged withintervening spaces below the normal water line, and a strong networkforming part of the sides of the ship below the water line whereby waterhas access to the spaces between the tanks.

2. A ship comprising a series of airtight tanks arranged withintervening spaces below the normal water line, a series of watertightcompartments above the water line and arranged between upper and lowerdecks,

, and a strong network forming part of the sides of the ship below thewater line whereby water has access to the spaces between the tanks.

in testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
